Designed to give your bass a thunderous fuzz or distortion, the Mooer Thunderball is a teeny tiny pedal thats size belies its sound. With both a distortion mode and a fuzz mode housed in its miniature chassis, the Thunderball can serve up classic fuzz calibrated specifically for the bass and a warm, vintage distortion that will add gain without covering or destroying your organic sound. Intuitive volume, tone, and gain knobs give you control over your fuzz or distortion for an easy-to-use, great-sounding, impressively inexpensive pedal from Mooer.
